Guernsey gave its name to a sweater: the Guernsey (or gansey) jumper. Thicker and warmer than a jersey, Guernsey sweaters were knitted for seamen as long ago as 1468, when the island was granted a charter to import wool. Still hand-finished on the island today, they are unique, stylish and practical: Packed fibers and a tight knit repel rain and spray, and they have shoulder gussets and splits at the hem for ease of movement.
